Discovery Green expands portfolio with renewable energy deals with Implats, KP Lime and leading hospitality brands

Discovery Green is pleased to announce the signing of five new clients in the mining, property and hospitality sectors, securing long-term partnerships with Impala Platinum Holdings Limited (Implats), KP Lime, The Capital Hotels and Apartments, Balwin Properties, and Fortress REIT Limited. The signing of these agreements aligns with Discovery Green’s mission to provide affordable and price-certain renewable energy to businesses in South Africa, advancing the country’s transition to cleaner, more sustainable energy solutions.

The power of collaboration

The agreement with Implats marks a significant milestone in Discovery Green's portfolio. Starting in 2026, a five-year PPA will supply 90% of the electricity needs for Impala Refineries in Springs, Gauteng. This agreement will reduce Impala Refineries' Scope 2 greenhouse gas (GHG) emissions by more than 852,000 tonnes of CO₂e over five years and deliver significant cost savings on over 130 000 MWh of electricity per annum.

Patrick Morutlwa, Group Chief Operating Officer at Implats, said: “From 2026, the PPA will reduce our Scope 2 GHG emissions by 170,484 tonnes CO₂e per year and advance our goal of achieving a 30% reduction in carbon emissions by 2030, off 2019 as our baseline year. The agreement with Discovery Green aligns with our decarbonisation and energy security strategy to adopt renewable and low-carbon energy sources and contributes to achieving several of the United Nations’ Sustainable Development Goals.”

Discovery Green also signed a deal with KP Lime, a market leading producer and distributor of burnt lime and dolomite. The 10-year power purchase agreement (PPA) will supply 54,000 MWh of renewable energy annually to the Bowden mine in the Northern Cape. This agreement will replace over 90% of the mine’s energy needs with renewable energy, delivering significant cost savings and contributing to the mine’s sustainability goals.

Aneesh Misra, CEO of KP Lime, said: “At KP Lime, sustainability is at the core of our operations, and this initiative aligns closely with our group company, IMR Metallurgical Resources AG’s global commitment to sustainability and environmental responsibility. We are thrilled to partner with Discovery Green on this impactful journey, which strengthens our efforts to minimise environmental impact and supports the growth and sustainability of the South African economy.

“With Discovery Green’s remarkable 90% renewable energy coverage, we can significantly reduce emissions while achieving meaningful operational savings. By signing this agreement, we are reinforcing our dedication to advancing sustainability on a global scale, demonstrating that environmental stewardship and business success can go hand in hand.”

Andre Nepgen, Head of Discovery Green, added: “The agreements with KP Lime and Implats are a significant step towards South Africa’s energy transition and highlight the power of collaboration in addressing climate challenges. By integrating renewable energy into their operations, the mines can advance decarbonisation and position themselves for competitiveness in a low-carbon economy. Discovery Green is proud to support forward-thinking organisations, like Implats and KP Lime, in building a resilient and sustainable future.”

Key players in the property and hospitality industries are also set to benefit

Discovery Green also finalised long-term agreements with The Capital Hotels and Apartments, Balwin Properties, and Fortress REIT Limited last quarter.

A 15-year agreement with The Capital Hotels and Apartments will supply 5,000 MWh of renewable energy annually to three of The Capital’s properties in Gauteng.

Marc Wachsberger, Founder and CEO of The Capital Hotels and Apartments, said: “We constantly evaluate our sustainability strategy, including reducing our carbon footprint by exploring alternative green energy sources. Discovery Green’s offering stood out as the best in the market with its high coverage level of 90% replacement of consumption and flexible, platform-based contracting. We’re excited to partner with a trusted South African brand that can also provide a one-stop shop for our renewable energy needs.”

In a 20-year contract signed with Balwin Properties, Discovery Green will supply renewable energy to four Balwin sites, totalling 13,600 MWh annually.

Steve Brookes, CEO of Balwin Properties, commented: “The partnership between Balwin and Discovery Green embodies our commitment to sustainability and innovation. This collaboration aligns the provision of clean, renewable energy with peak usage times for our residents, all under a financial model that offers savings compared to municipal rates.”

The agreements follow a 10-year wheeling arrangement with Fortress REIT Limited, a leading property group. Discovery Green will wheel renewable energy to 14 Fortress properties, increasing Fortress’s renewable energy penetration up to 100% in these buildings.

Steven Brown, Fortress CEO, commented: "We are proud to partner with Discovery Green on this initiative. This wheeling agreement is critical in reaching our 2030 decarbonisation target."

By partnering with Discovery Green, the companies are positioned to replace more than 90% of their electricity demand with renewable energy wheeled from the largest wind and solar plants in South Africa, saving a total of 39,000 tonnes of CO₂e emissions annually. The transition to renewable energy allows the companies to avoid escalating electricity costs, which are rising faster than inflation, and mitigate the impending impact of carbon taxes.

“These partnerships highlight our commitment to supporting sustainable business growth and resilience, helping companies remain competitive in an increasingly dynamic market,” said Andre Nepgen, Head of Discovery Green.
